BRACKETS [PDF]

open access: yesInternational Journal of Geometric Methods in Modern Physics, 2013
We review origins and main properties of the most important bracket operations appearing canonically in differential geometry and mathematical physics in the classical, as well as in the supergeometric setting. The review is supplemented by some new concepts and examples.

Evaluation of the remineralisation of the demineralized enamel surrounding orthodontic brackets using the nano hydroxyapatite: An original study

open access: yesJournal of Pharmacy and Bioallied Sciences, 2023
Introduction: The orthodontic appliances have been known to accelerate enamel loss due to various reasons. Since there are few studies supporting the role of the nano-HAP in the mineralization of the demineralized tooth surfaces, the current study ...

Effect of Lactobacillus casei shirota strain probiotic beverage on the release of chromium ions in stainless steel brackets

open access: yesPadjadjaran Journal of Dentistry, 2023
Introduction: Stainless steel brackets are often used in orthodontic treatment. Chromium is one of the stainless steel bracket elements that increases corrosion resistance. Chromium ions’ release can cause allergic reactions.

Twisted C‐Brackets

open access: yesFortschritte der Physik, 2022
AbstractWe consider the double field formulation of the closed bosonic string theory, and calculate the Poisson bracket algebra of the symmetry generators governing both general coordinate and local gauge transformations. Parameters of both of these symmetries depend on a double coordinate, defined as a direct sum of the initial and T‐dual coordinate ...

Kaestner brackets

open access: yesTopology and its Applications, 2020
We introduce \textit{Kaestner brackets}, a generalization of biquandle brackets to the case of parity biquandles. This infinite set of quantum enhancements of the biquandle counting invariant for oriented virtual knots and links includes the classical quantum invariants, the quandle and biquandle $2$-cocycle invariants and the classical biquandle ...
